UNITED STATES PATENT OEEicE GEORGE L. MARTIN, OF NEV YORK, N. Y.

MARINE ELECTRIC-LIGHT FlXTURE.

SPECIFICATION forming part of Letters Patent No. 649,250, dated May 8,1900.

Application filed December 4, 1899. Serial No. 739,163- (NO 111051613 To@ZZ whom it may concern:

Be it known that I, GEORGE L. MARTIN, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented new and useful Improvements in Marine Electric-LightFixtures, of which the following is a specification.

My invention relates to marine electric-light fixtures; and the objectsthereof are, first, to produce a fixture which shall be perfectlywater-tight; second, to provide an effective switchingapparatus withinthe fixture; third, to provide a fixture which can be manufactured morecheaply than those now on the market. I attain these objects by themechanism illustrated in the accompanying draw ings, in which-- Figure 1is a marine electric-light fixture, partly in section, constructedaccording to my improvements. Fig. 2 is a plan view of the box with theswitch located therein, and Fig. 3 is a bottom plan view of thebracketbase.

Similar numerals of reference refer to like parts in each of the views,and in the practice of my invention I provide a box of peculiarconstruction, consisting of a solid unperforated base 5 and an annularrim 6, on which are formed three bosses 7, 8, and 9, through two ofwhich pass the service-pipe and which are secured therein in awatertight manner. The third boss maybe bored and tapped to providemeans of communication with a branch light,if desired. External lugs 11are provided, so that the box may be secured to a support withoutpassing screws through the box. Within the box are a plurality of posts12, each of which is provided with a tapped recess 13, adapted toreceive a screw 14:, by which the bracket may be secured thereto, and agasket 15 serves to make a water-tight connection. The bracket consistsof a base 16, which is provided with apertures through which pass thescrews 14, and the base 19 is provided with a plurality of prongs 18,adapted to pass through the gasket 15, as shown in dotted lines in Fig.1, and by reason of this construction gaskets can be readily made out ofany piece of sheetrubber or other packing material, and the prongs willcenter the same when being placed in position. The bracket furtherconsists of an elbow 19 and a headpiece 20. The elbow 19 is preferablythreaded externally, and the base 16 and head 2O are provided withthreaded apertures to engage the same.

The head 20 is preferably cast in one piece and is provided with anintegral liange 21, on which is mounted the electric lamp 22. A glassglobe 23 is screwed into the outer end of the head 29 and bears upon agasket 2i, mounted on the iiauge 21, whereby a watertight connection isformed, and a guard may be used to protect the globe 23 and lamp.

Since it is desirable that the switch should also be inclosed within thefixture, I have `provided a switch especially adapted for use in afixture of this kind, consisting of a plate 26, composed of liber orother suitable 1nate.

rial and adapted to tightly fit between two of the posts 12, preferablyon the side of the box opposite to the boss 9. On the plate 2G I mounttwo spring contact-plates 27, each of which connects with acorresponding binding-post 2S, and the opposite end or free end of eachplate is bent to form a hook 29. A shaft 30 carries a contact-ring 31 atits inner end and is mounted in a water-tight manner in a boss 32 on therim 6. The boss 32 is provided with an inclined face 33, and a pin 34 onthe shaft 39 contacts with said face and when the shaft 30 is rotateddrives the said shaft outward against the action of a spring 35 andcarries with it the ring 31 until it contacts with both hooks 29 of theplates 27, when of course the current will pass, and a notch 36 in theouter end of the boss 32 serves to hold the ring 31 in contact with thehooks 29, as will be readily understood.

In operation the Wires are passed into the box through the service-pipey10, and connection is made with the binding-posts 28. Wires are passedfrom there through the bracket to the electric lamp,and connectionwillbe made, so as to pass the current to the lamp by" rotating theshaft 30, so as to bring the ring 31 into contact with the hooks 29 ofthe plates 27, as will be readily understood.

I do not confine myself to the exact construction or arrangement ofparts here disclosed, nor do I conine myself to the use of the box andswitch with the kind of bracket IOO herein disclosed, for the sha-pe ofthe bracket would depend largely on the position on shipboard where thefixture was to be located.

llaving thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A marine electric-light fixture, comprising a box having externallugs 11, internal posts 12, with tapped recesses 13, a bracket mountedon said box by means of screws 1i engaging said tapped recesses, prongson the base of said bracket, and a gasket mounted on said prongs betweensaid bracket and said box, said bracket consisting of a base 16, elbow19, and head 20, substantially as andv for the purpose described.

2. In a marine electric-light iixture,a switch mounted within the box, aboss on said box having an inclined outer face, a shaft entering saidbox through said boss, and carrying a pin adapted to engage saidinclined face whereby contact is made in said switch, for the purposeset forth.

3. In a marine electric-light fixture of the character described, a boxconsisting of base 5, rim 6 having bosses 7, 8, 9 and 30, said boss 32having an inclined outer face, said box being provided with externallugs 11, and internal posts 12, having tapped recesses 13, substantiallyas and for the purpose set forth.

In a marine electric-light Lixture, the

combination with an outlet-box, having a base 5, rim C with bosses 7, S,9, and 32, external lugs 11, and internal posts 12, with tapped.recesses 13, of a switch mounted within the box and supported by saidposts, said switch consisting of a plate 26, plates 27 having hooks 29,binding-screws 2S, a shaft 30 carry ing ring 31 adapted to contact withsaid hooks, and means to throw said ring into contact with said hooks,for the purpose set forth.

5. 1n a marine electric-light fixture, thev combination with anoutlet-box, having a base 5, rim 6 with bosses 7, 8, fl, and 32, external lugs 1l, and internal posts 12 with tapped recesses 13, of aswitch mounted within the box and supported by said posts, said switchconsisting of a plate E26, plates 27 having hooks 2D, bindingscrews 28,a shal't 30 carrying ring 31 adapted to contact with said hooks, andmeans to throw said ring into contact with said hooks, consisting of apin inserted in said shaft, and said boss 32 having` an inclined outerface adapted to engage said pin and move the said shaf t longitudinally,substantially as and for the purpose described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE Ti. MARTIN.
